The clipper design is really great, even for bike users. The fact that it clips on clothes or on a backpack avoids having to attach and detach them on your bike every time you use it, or forget them on the bike in the cold during winters.
The only problem I saw was the resistance of the clip. one of mine broke on the weakest point (see photo below) and fell off after 3 months of use, and can't be repaired easily.
It was quite a good deal but not worth the price for such a short period.

It was a very helpful Tool. Especially running ore cycling now in autum when it was not yet really dark. Gave me a good feeling to be visible !!
These small lights are a good touch for evening dog walks now that days are getting shorter
The lights are great but last 120 minutes max. I need two front lights to make it through my longer runs.
